'SPRING-MATTRESS AND SPRING SEATING-SURFACE.

Specification of Letters Patent.

Patented July 7, 1914.

Application filed October 27, 1913. Serial No. 797,630.

To all 'whom it may concern Be it known that I, JOHN EDMUND MansnALL, asubject of the King of Great Britain, and a resident of Sandiacre,Derbyshire, in England, have invented a certain n ew and usefulImprovement in or Relating to Spring-Mattresses and Spring Seating-Surfaces, of which the following is a specification.

This invention relates to spring mattresses, the seating surfaces ofrailway carriages, motor buses, motor cars, and the like, and refers toimproved means for connecting together the respective springs comprlsinga mattress or seating surface.

The invention is applicable to mattresses or seating surfaces which arebuilt up of a series of vertical springs connected to each other, saidsprings being if required, sayin the case of seating surfaces,. inclosedby upper and lower external wire frames, which constitute the stuthngedges.

' Referring to the drawings, Figure 1. is a sectional elevation, andFig. 2. a plan showing part of a spring seating surface constructedaccording to my invention.

Like letters indicate like parts throughout the drawings.

The present invention refers to mattresses or seating surfaces, whichare built up of a series of vertical springs set close together andconnected to each other throughout their full length. This constructionhas hitherto been eected by interlacing the respective coils of each ofthe springs, with the corresponding coils of the contiguous springs.

According to the present invention, the springs comprising a mattress orseating surface such as described, are secured to each other byconnecting the coils of each spring to the coils of the contiguoussprings, by means of a length of leather, tape braid, or like flexiblematerial, which not only serves to secure the springs together, but isdisposed so as to prevent the coils from coming into contact with andrubbing against each other.

As shown in the drawings, a length of flexible material B starting sayfrom the bottom, is interlaced or carried through the coil of first onespring A and then the other, until the top is reached, and after beingpassed around the upper coils of both springs A, it is returned to thestarting point. In returning, the material B is as shown carried aroundthe first part which is interlaced with the coils, between each of thelatter, and after being carried around the lower coils, the two ends ofthe material are secured together.

The length of flexible connecting material B when arranged as described,forms a non-metallic buffer between each and all the spring coils, andthus prevents them from rubbing together and making the noise which isinseparable from such action. The whole of the springs A are furthereffectively and flexibly secured together throughout their length,forming a compact mass, but the connection is of such a nature thatlocal pressure is not extended over a wide area, and the surroundingsprings are not therefore pulled over toward those depressed.

The external frames D and E which constitute the upper and lowerstuffing edges, may be connected to the upper and lower coils of themarginal springs A in the usual manner, that is, by lacing or connectingthe said coils to the frames D and E in the usual manner. y

lVhat I claim as my invention and desire to cover by Letters Patent is:H

l. A spring seating surface built up of a series of vertical springssecured together by connecting the coils of each of the springs to thecoils of the contiguous springs by means of a length of flexiblenon-metallic material engaging alternately with the coils of bothsprings, substantially as described.

2. A spring seating surface, comprising a series of helical springsarranged side by side, and stretches of flexible material connecting theadjacent portions of the said springs and extending longitudinally ofthe springs between their coils.

3. A spring seating surface built up of a series of vertical springssecured together by connecting the coils of each of the springs t momento the coils of the contiguous springs by means of a length of iexiblenon-metallic material which is rst interlaced With the coils of bothsprings then returned and f5 crried around itself between the coils andthe two ends secured together sbstantiadly,

as described.
